摘要

应用随机振动理论

对浮动式钻井装置在随机海浪作用下的动力响应进行了分析。在分析研究现在常用力学模型的基础上

建立了多自由度分布质量模型。应用谱分析方法

求出了系统的动力响应

进而得出由于系统振动而作用于大钩、升沉补偿装置及井架上动载的计算公式

为精确分析整个系统的疲劳强度及疲劳寿命提供了理论依据

Abstract

The vibration responses of floating drilling vessels in random sea waves are studied in this paper by using the theory of random vibrations.On the basis of analysis of previous mechanical models

a multi degree model with a distributed mass is established.The dynamic responses of the system are obtained by using the spectral analysis method.Furthermore

the computational formulae are given for dynamic loads of hook

heave compensation system and derrick.This work provides theoretical support for fatigue strength and fatigue life analysis of the system.
